Abstract

The technical capabilities of LZOS allow optics manufacturing from the phase of melting and annealing of Astrositall blanks to their final figuring. Now LZOS is working on the several large contracts, among them are manufacturing of 96 hexagonal segment blanks of 1019 mm x 55 mm of Sitall CO-115M for the SALT (Southern African Large Telescope) primary segmented mirror, and 40 sub-mirrors of Zerodur for the 6.7 m x 6 m segmented M_B mirror for the LAMOST (Large Sky Area Multi-Object Spectroscopic Telescope) project.
